Embodiment Construction

[0011] Depend on figure 1 It can be seen that the specific composition of the multi-stage magneto-rheological damper of the present invention is: the front cover 8 and the rear cover 2 are respectively installed on the shaft 1 with a disk in the middle through the bearing 10, and the housing 7 is sleeved on the front and rear covers. The magnetorheological fluid 12 is placed in the cavity formed by the front and rear covers, the seal 11 and the shaft 1 . Its characteristics are: 12 independently working electromagnetic components are installed in equal parts in the cylindrical inner cavity between the front cover 8 and the rear cover 2, and each electromagnetic component is fixed on the front cover and the rear cover with positioning pins through the magnetizer 3 superior. The insulating material 4 is wrapped in the outer layer of the wire, and the wire 6 of the coil is connected with the RS232 interface 13 . The snap ring 9 separates the magnetorheological fluid from the el...

Abstract

The magnetic current damper is composed of the shell, the front shield, back shield, the shaft with the disk and magnetic current liquid. The coiled slug, magnetizer and 12 electromagnetic element made of insulating material working independently are installed in the columned cavity between the front and back shield. Different from the existed damper, the damping force is changed according to the change of the magnetic field area, which is applicable for the rotary apparatus and high frequency field.

Description

Technical field: [0001] The invention relates to a multi-stage magneto-rheological damper. Background technique: [0002] There are generally three methods of using magnetorheological fluid to generate damping force: 1. Pressure mode, that is, using external pressure to make magnetorheological fluid pass through the channel between two fixed plates. When a magnetic field perpendicular to the plate is applied, the magnetic The viscosity coefficient of the rheological fluid increases, thereby increasing the resistance when the magnetorheological fluid flows; 2. Shear type, that is, the magnetic field is perpendicular to two parallel plates. When the two plates move relative to each other, the magnetorheological fluid under the action of the magnetic field 3. Squeeze type, that is, the magnetorheological fluid under the action of the magnetic field is squeezed by changing the distance between the upper and lower plates to generate damping force. [0003] At present, the widely...
